Monthly Microbes: The oldest (3.8 billion or possibly 4.2 billion!) microbe fossils reported in the March 2, 2017 issue of "Nature", were found in ancient hydrothermal vents in Quebec. The fossils contained micrometer-sized tubes similar to modern day filamentous microorganisms. Source: Dodd, M.S. et. al. Evidence for early life in Earth’s oldest hydrothermal vent precipitates.

Bioengineering Banter#5: Bacterial Generators?!?!? A recent report in "Cell" shows that Shewanella oneidensis can be converted into little generators. Researchers fed a chemical additive (DSFO+), that contains iron in its core, to modify the cell membrane of Shewanella oneidensis to be able to efficiently conduct electricity. While the amount of electricity produced is minimal, the thought is to give bacteria at waste water treatment plants multiple jobs: produce electricit
